P207E Intake Manifold Tuning (IMT) Valve Position Sensor/Switch Circuit Intermittent (Bank 2)

Bank 2 version of the intermittent feedback fault: the valve position signal drops out or jumps for short moments, but returns to normal between events. No manufacturer documents P207E, and even its bank 1 twin P2079 has no published OEM use with this meaning. The diagnosis is therefore generic: since the fault may vanish before a scan tool is connected, freeze-frame data and the failure counter help to judge how often it happens. Heat cycling on the rear bank, vibration and water in the connector are the usual triggers. If the signal fails permanently, the code typically turns into the circuit or low/high variants P207A, P207C or P207D, which are easier to pinpoint.

Likely causes

Symptoms

• Intermittent warning light (manufacturer-dependent)
• Fault not reproducible in the workshop

Repair estimate

Typical range across vehicles; the real cost depends on what the testing finds.
